Serious question - why?
Why would you not want people to produce software for Linux?
Pride? Too much respect for a long standing feud?
Although, from some of the sibling comments, perhaps I've underestimated its popularity?
Probably because Google already did all the hard work -- it's a Chrome fork -- and it's good press in tech circles.
Unlikely IE, edge its been a widely used browser since its good as chrome so people don't have the need to switch browser, so it have to be tested
Now we can expect apple release safari to linux? I don't expect this so soon.
